Abstract
The purpose of the study was to find out the significant difference of Explosive Strength and Maximum
Leg Strength between National Level Wrestlers and Judokas. For present study, total 30 male national
players (15 each from judo and wrestling) with their age ranging between 19-27 years was selected
randomly from Punjabi university, Patiala affiliated colleges. The explosive leg strength measure with
the help of standing broad jump and maximum leg strength measure with the help of leg dynamometer.
Unpaired t-test was employed. The level of significance 0.05 was set. The result shows that insignificant
differences in both variables between National Level Wrestlers and Judokas.
Keywords: Explosive strength, maximum leg strength, wrestlers and judokas
Introduction
Judo is an Olympic sport where to perform inferior body actions need a certain explosive
strength determined as much for the movement of athletes by tatami as for the implementation
of technical entries, as for opposition to the opponent’s activities. According to Stone et al.
(2003) [5]
the most critical aspects of sports performance occur in a very little time period (250
ms), therefore athletes develop abilities to produce larger amounts of force within this time,
would reach to get a faster acceleration and higher speed. So it is unstated that the chance of
applying more force in the shortest time possible when perform a specific act (either in arms or
legs), is an attribute that can determine a success event at any time of a judo combat. However,
the inability to evaluate quantitatively the explosive strength of inferior limb with several
particular combat judo movements, becomes necessary to use a test, although non-specific, to
determine the motor pattern of manifestation on the strength in the inferior limbs (Monteiro, et
al., 2014) [3]
.
It is clear that manifestation of the explosive force in the lower limbs (e.g., without
countermovement jump) result: (1) combining the contractile capacity, understood as the
concentric action of the agonist muscles without the use of muscle stretch-shortening cycle -
SSC (Gollhofer et al., 1987) [2]
; and (2) the synchronization ability of the contraction of the
fibers. However, it’s currently accepted that the participation of the SSC increases the
mechanical efficiency of the movements, that using followed eccentric muscle actions
(immediately) by explosive concentric actions. This justifies the utility of expression elastic-
explosive evaluation with recourse to countermovement jump (CMJ). The objective of this
work is to analyze the levels of explosive lower body strength through the SJ and CMJ to
observe differences between Top-Elite judokas and Elite judokas.
Explosive strength is a combination of strength and speed abilities. It can be defined as the
ability to overcome resistance with high speed. It depending on the nature of combination of
strength and speed. It is a form of dynamic strength, the following strength measures under
study are: Explosive arm strength and Explosive leg strength (Singh, 2012) [4]
.
Explosive strength always finds expression in motor movement. A high percentage of
movements in sports are of explosive nature and Involves overcoming of some external or of
one's own body weight. Explosive strength therefore, is important in most of sports. It can be
defined as the ability to overcome resistance with high speed. It is shown clearly in activities
such as throwing and Jumping when athletes attempt to project themselves or an object as far
and as fast as possible Explosive strength is readily measurable leg strength or power can be

assessed either by a vertical leap or a standing broad jump.
Here we present some examples in which explosive strength
plays 'important role, start in sprint races, start in swimming,
smashing in volleyball, goal shooting in handball, long jump,
high jump, throws, fast bowling in cricket hitting six in
cricket, most of the movement in kho-kho, smashing in
badminton and tennis and so on wrestling weight lifting also
require explosive strength It is the use of explosive strength
that makes these sports Interesting exciting and popular not
only among the sportspersons, but among the common people
as well.
Methodology and Procedure
For present study, total 30 male national players (15 each from
judo and wrestling) with their age ranging between 19-27
years was selected randomly from Punjabi university, Patiala
affiliated colleges.
Selection of Variables
Variables selected for this study were:
1. Explosive leg strength
2. Maximum leg strength
Criteria of Measurement
1. The explosive leg strength measure with the help of
standing broad jump. The subject is given three trials. The
best trial is used as the final score of the test.
2. The maximum leg strength measure with the help of leg
dynamometer.
Statistical Procedure
Unpaired ‘t’ test was applied to find out the difference or to
compare mean, standard deviation and standard error mean
was computed to describe each variable statistically. The level
of significance was set at .05.
Results and Discussions
Table 1: Comparison of Mean and Standard Deviation of Explosive Strength between
National Level Wrestlers and Judokas Players
Group N Mean Standard Deviation Standard Error mean t-value
Wrestlers 15 2.25 0.28 0.07
1.20
Judokas 15 2.14 0.21 0.05
‘t’.05 (28) = 2.048
Table 1 statistically depicts that the mean and standard
deviation with regard to Wrestlers national level players is
2.25 and 0.28 where as in case of Judokas national level
players is 2.14 and 0.21 respectively. The calculated t-value
(1.20) which is less than the tabulated t-value (2. 048) at 0.05
levels. So, it indicates that there is insignificant difference
between wrestlers and judokas national level players for their
Explosive strength variable.
Table 2: Comparison of Mean and Standard Deviation of Maximum Leg Strength between
National Level Wrestlers and Judokas Players
Group N Mean Standard Deviation Standard Error mean t-value
Wrestlers 15 157.80 26.67 6.88
0.58
Judokas 15 164.53 35.90 9.27
‘t’.05 (28) = 2.048
Table 2 statistically depict that the mean and standard
deviation with regard to Wrestlers national level players is
157.80 and 26.67 where as in case of judokas national level
players is 164.53 and 35.90 respectively. The calculated t-
value (0.58) which is less than the tabulated t-value (2.000) at
0.05 levels. So, it indicates that there is insignificant difference
between wrestlers and judokas national level players for their
maximum leg strength variable.
Discussion of the Findings
Explosive Leg Strength: It was found that there was
insignificant difference of explosive leg strength variable
between national level wrestlers and judokas players. Because
Judo and wrestlers including in same type of training and they
do approximately same types of training that is why they do
not show any significant difference in their explosive leg
strength. These findings are supported by Bhat and Biswas
(2015) [1]
“A Comparative Study of Explosive Leg Strength
and Maximum Leg Strength of Different Categories of Men
Sprinters”.
Maximum Leg Strength: The results of the study notify that
there was insignificant difference between national level
wrestlers and judokas players for their Maximum Leg
Strength. Because Judo and wrestlers including in same type
of training and they do approximately same types of training
that is why they do not show any significant difference in their
Maximum leg strength On the basis of analysis of the data,
investigator found that the earlier study of Bhat and Biswas

and Maximum Leg Strength of Different Categories of Men
Sprinters”.
